To all 'rr/1,0m t may conc/27%:

Bc it known that I, ADOLPH F. SCHRAMM', a citizen ot' the United States, residing at Columbus, in the county of Franklin and State ot' Ohio, have invented a certain new and usetul Improvement in VehicleSeats, ot' which the following is a specification.

This invention relates more particularly to seats in which the back moves up and down with the seat and its Objectis to provide an improved and simplified construction in which the back moves down by gravity and up by the rebound of the seat; a further object is a construction in which the back can be readily attached and detached.

The invention is embodied in the exam-ple herein shown and described, the features of novelty being particularly pointed out at the close of the description.

In the accompanying drawing, Figure 1 is a front View with the upholstery of the back removed. Fig. 2 is a view looking at the right hand end of Fig. 1, parts being in section to show details of construction.

In the views 5 designates the rear, 6 the bottom and 7 an arm or end of the main frame. The frame can be curved from the back to the arm. Upon the bottom 6 is removably placed a cushioned seat which includes suitable upholstering springs such as shown at 8, a wired edge 9 and suitable covering 10.

Upon the rear portion 5 of the main frame are secured plates 11 provided with slots 12 terminating at their lower ends in enlarged circular' openings 13.

The vback comprises a suitable frame which can be curved if desired to conform to the main frame. The lower strip of the back frame israther wide and is designated 14, amlhllras added to it a narrowerstrip 15 so :is t'b form an angle or rabbet to lit upon and engage the wired edge of the seat..

The rear portion of the back vframe is provided with a metallic strip 16 containing a pair of studs having heads 16, said studs being so located that when the back is lowered 'to or near the bottom 6 of the 'i main frame they can be inserted or removed from the enlarged opening 13. When the studs have been so inserted the back can be raised to its normal position. The back is held supported in normal position by the seat after that member has been placed lin position on the bottom of the main frame.4 The back frame is, of course, suitably upholtered by means of springs suitablycovere The opening between the upper edge of the main frame andthe back can be covered to prevent the access of dust etc. by means of a flexible piece 17 secured to the sliding back and buttoned or otherwise attached to the back of the main frame. This covering piece 17 should be of ample width to permit the vertical reciprocations of the back.

The arm of the main framey can be upholstered independently of the seat and back, care being taken to do this in such a wayvas not to perm-it abrasion of the moving parts with such upholstering.

This construction is particularly useful in motor vehicles and when the seat is occupied by a rider the back rises and falls with the elevation and depression from normal of the seat. The uncomfortable abrasive action of the seat on the back of the rider is thus avoided.

What I claim is- 1. The combination with a main frame including a rear upright portion, of a yielding seat and a back slidingly connected with said rear upright portion to have a rectilinear' movemeiit but not connected with the seat and resting by gravity upon the rear edge of the seat.

2. The combination with ai main frame including a rear upright pol'tion, of ayielding seat, and a back removably but slidingly connected with said rear frame to have aA rectilinear movement but not connected with the seat and resting by gravlty upon the rear edge of the seat.
